I mainly use the Particle IDE software for coding.
I use the Photon and Electron.
I just do a Particle.publish with event name I have setup in the Losant Particle Integration. It's super simple to get data into Losant using the Particle Publish which is always working except when Particle has issues here and there which usually gets resolved quickly.
Are you using the Particle Integration with Losant?
What kind of issues are you having?
